ADJUSTABLE GUARD=RAlL FASTENER- Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed April 11. 1906. Serial N01 311.045-

i (all whom it may concern.-

Be it known that I, CLARENCE C. KonNs, oi Johnstown, 1n the county ofCambria and State of Pennsylvania, have invented a new i and usefulimprovement in Adjustable Guard- Rail Fasteners of which the followingis a i full clear and exact descri )t-ion reference 1 i spectlvely,while the member G 1s provided being had to the accompanying drawings,which form a part of this specification.

This invention relates to certain new and useful improvements inguard-rail fasteners; and it has for its object to provide a simple,cheap, and eflicient device of this character which will firmly hold theguard-rail in its proper relation with the main rail and which can beadjusted without withdrawing the guard-rail in order to adjust the chockmembers.

W'ith these objects in view my invention consists of the novelconstruction, arrangement, and combination of parts, all substantiallyas hereinafter described, and pointed out in the appended claims,reference being had to the accompanying drawings, in which Figure 1 is aplan view of a main rail and a guard-rail with my improved chockattached thereto. Fig. 2 is a sectional view on the line 2 2 of Fig. 1.Fig. 3 is a perspective view of the chock members shown in Figs. 1 and2. 4 is a plan view of a modified form of chock. Fig. 5 is a sectionalview on the line 5 5 of Fig. 4. Fig. 6 is a plan view of MlOLl'lGlmodified form of chock, and Fig 7 is a sectional view on the line 7 7 ofFig. 6.

A is the main rail, A the guard-rail, and B and C are the chock members.The rails A A and the chock members B and C are rigidly held together bymeans of the bolt E and nuts 0 (a, the bolt E passing through orificesin j tongue-and-groove connectlons.

the rails A A and elongated orifices b and c in the respective chockmembers B and C. The chock members B and C are tapered or wedge-shaped.The member B is provided with the groove 1), which is slightly taperedin cross-section, while the member C is protitled with a tongue 0, whosecross-section is of the same taper as the cross-section of the l l l E 1l l l l l j l l l l l i groove 6, but slightly greater in width than thew dth of the groove.

In Figs. 4 and 5 the chock is composed of the three tapered members F,G, and H, provided with the elongated slotsf, g, and h, respectively,the members F and H being provided wlth tapered grooves f f and h it,re-

with the tapered tongues g g on each side thereof, the tongues g g onone side of the member G entering the grooves f of the member F, and thetongues g g on the other side of the member G entering the grooves h hof the member H.

In Figs. 6 and 7 the chock is composed of the four tapered members F, H,J, and K. The tops and bottoms of the members J and K are chamfered andare inserted into the respective grooves and h of the members F and G.

It will readily be understood by reference to the drawings that when therails and chock members are bolted together the chock members will belocked from vertical movement by means of the tongue and groove and willbe held from horizontal movement by the frictional engagement of thetapered portion of the tongue and groove.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. An adjustable chock, tapered chock members provided with aninterlocking tapered tongue and groove.

2. An adjustable chock, tapered chock members provided with aninterlocking wedge-shaped tongue and groove.

3. An adjustable rail-chock having a plurality of wedge members,provided with wedge shaped frictionally interlocking In testimonywhereof I have afiixed my signature in presence of two witnesses.
